At the'left Vhand side of Fig. 1 it will be noticed that the plate or member`18 extendsV a vgreater distance from the screw `head1@ toy the edge`22, engaging electrotype E than the extension of said member 18 from ,said

screw head 16 to the edge 20.` VIt may be desirable to transpose theseV electrotypes E" and E land suchtransposed electrotypes may be secured in place by reversing the positions of the edges 20' and 22 Vof. the member 18.

It may also be desirable to substitute other,

slightly larger electrotypes for those shown atsaid left hand siede of Fig.f1 and suchl larger electrotypes may be received by givingthe members 17 17 a one quarter rotation to bring the'edges 19 and 21 in position to.
